did you try other movies first, could be just the levels in that movie were not correctly edited. I've seen big differences in volume levels of different programs on my Apple 4k tv, mind you I do not use a surround processor. I go USB to a DAC for two channel.
AppleTV Atmos levels seem off
Hello all, i recently switched to AppleTV 4k. So far so good, but…. Last night i was streaming The Suicide Squad. My Denon showed DolbyAtmos, the pic was UHD as promissed too.
My subs are usually good at -2.5db, my MV is usually -15 to -10 its a good sounding system, but i had to raise my MV to 0db and my sub level to +5db, it sounded like usual once those changes were made.
My denon is the x4300
